How to fix coolant leak

Use a flashlight or rent a coolant pressure tester from your local auto parts store. We can't see the engine or leak, so you will need to get help from a friend or mechanic if you can't find it yourself. It can be from the water pump, thermostat housing, a hose, etc.

Also check frost plugs and block heater if it has one.
